If Griffin still has doubters left, that's their problem. He turned heads at the Senior Bowl with his versatility, and his remarkable story just keeps getting more amazing. His twin brother, Seattle Seahawks' 2017 third-round CB Shaquill Griffin, clocked a 4.38 last spring... at 6-foot-0, 194 pounds. Shaquem Griffin measures 6-0 and 227 pounds and is tied with North Carolina State RB Nyheim Hines (5-foot-8, 198 pounds) for the third-fastest 40 time by any prospect through three days.
